The final rinse solution can be provided in concentrated form, particularly because the glycol is included.

  • Patent number: 5928844
    Abstract: A color photographic silver halide material is processed effectively without formation of rust after the bleaching step. Bleaching is accomplished using an iron chelate of a biodegradable aminopolycarboxylic acid chelating ligand that has a tendency to form "rust" or ferrous hydroxide in processing baths conventionally used after bleaching, such as washing solution. This tendency to form rust is overcome by spraying the bleached film with a washing solution before fixing, and without immersion of the film in that washing solution.

  • Patent number: 5866633
    Abstract: A biocidal material comprises an organic biocide immobilized on a polymeric support characterized in that the support is water-insoluble and the biocide is covalently bound to the support by a hydrolytically stable covalent linkage. The material can be used for inhibiting bacterial growth in an aqueous medium e.g. the wash water of a photoprocessing system. The material can be housed in a flow-through container.

  • Patent number: 5856073
    Abstract: Silver halide photographic color films can be effectively stabilized using a chemical stabilizing kit of two concentrated chemical solutions that are mixed and diluted at least 5:1 when used. Each concentrated chemical solution contains some of the necessary chemicals for the processing solution, but keeping them individually packaged prior to use prevents biocide instability and other problems when all of the chemical components are mixed in concentrated form. One concentrated chemical solution includes hexamethylenetetramine and an alcoholamine such as diethanolamine. The other concentrated chemical solution includes the biocide(s) and one or more surfactants.

  • Patent number: 5853926
    Abstract: The present invention is an imaged photographic element having a protective overcoat thereon. The protective overcoat is formed by providing a photographic element having at least one silver halide light-sensitive emulsion layer; and applying an aqueous coating comprising polymer particles having an average size of 0.1 to 50 microns at a weight percent of 5 to 50 percent, a soft polymer latex binder at a weight percent of 1 to 3 percent, over the at least one silver halide light-sensitive emulsion layer. The silver halide light sensitive emulsion layer is developed to provide an imaged photographic element. The hydrophobic polymer particles is fused to form a protective overcoat.

  • Patent number: 5766830
    Abstract: A method for processing an exposed black and white silver halide photographic light-sensitive material includes the steps of: (1) developing the exposed light-sensitive material with a developing solution, (2) fixing the developed material with a fixing solution, (3) washing the fixed material with water which is replenished in an amount of from 0 to 3 liter/m.sup.2 of the exposed light-sensitive material, and (4) drying the washed material. The developing solution is replenished with a solid photographic composition. This solid photographic composition includes a developing agent selected from the group of a dihydroxybenzene developing agent represented by Formula I and a developing agent represented by Formula II (provided that the developing agent represented by Formula II may form a sodium salt, a potassium salt or a lithium salt). Formulae I and II are as follows: ##STR1## In the formulae, R.sub.1, R.sub.2, R.sub.3, and R.sub.
